Navigating a multi-part article in ios?-'you can't have intro/history on the left...' would using a different animation than left/right (drill-down,back) like up/down or page curl up/down be more suited for this kind of navigation since the user stays on the same level in the hierarchy ? - I also took a look at Reeder 'pull to go to prev/next' feature. it might fit in this scenario. - Would enforcing the order of navigation between the article's page make sense ?
